within the tongue to the apex, where it anasto::^ v.--with its neighbour. It supplies the submaxillary g:aii-I and the muscles of the tongue and suprahyoid reg:cn.
The facial artery (,tig. 27 E.M.A.j runs forward ! e-tween the submaxillary gland and mandible. At th-j anterior border of the masseter it gets into the faje where its course and relations are as in Man. Before it reaches the face it gives off a large artery to the sui-niaxillary gland (S.M.G.). In the face fig. 275 it ^ivei off masseteric, inferior labial ',.LL,A.}« inferior cr-ronarv (I.C.A,) and superior labial ;,S.L.A.« arteries to the I:^&. The submaxillary branch supplies the mylohyuld r^u^cle.
The superficial temporal artery (fig. 27, S.T.Y.' is the apparent continuation of the external carotid artery. It runs upwards along with the corresponding vein ana auriculo-temporal nerve. It divides into two vessels, which supply the scalp from the supra-orbital to the occipital crest.
The internal maxillary artery (fig. 30, LM.Aj arises within the parotid gland. It runs as in Man, and its relations are similar. It gives off the following branches:—
A. —In the Parotid Gland :—
(1)  Parotid arteries.
(2)   Transverse   facial   artery,   which   supplies   the parotid and masseter.
B.—In the Pterygoid Region :—
(1)   Branches to the pterygoid muscles.
(2)   Inferior dental artery (I.D.A.) which accompanies the inferior dental nerve.
(3)   ^leningeal artery (M.A.), which divides into middle and accessorv arteries.    These run into the skull as in

Man.
